IMPROVEMENT IN BRUSHES.

Specification forming part of Letters Patent No. 138,213, dated April22, 1873; application filed March 13, 1873.

To all whom tt may concern:

Be it known that I, PEILIPP WAGNER, of New York, in the county of NewYork and State of New York, have invented a new and useful Improvementin Brushes; and I do hereby declare the following to be a full, clear,and exact description ofthe same, reference being had to theaccompanying drawing forming part of this specication, in which- Figurel'represents, in perspective, the different parts of the brush head andhandle detached. Fig. 2 represents a sectional elevation of a brush.

The invention relates to the means for fastening the bristles of brushesso that they will bermly secured, and at the same time allowed a gooddegree of pliability. It consists in a metallic cap-disk, which preventsany ill etlect from the shrinkage of the wooden ring that holds thebristles down in socket. It consists, also, in forming a rib on theinside of socket so as to cause the ferrule to hold the bristles by alateral pressure against said rib, thus firmly retaining the bristles inplace.

In the drawing, A represents the bristles, and B the socket, againstWhose inner surface they are held by a metallic conical ferrule, F. Thewooden ring C has a central hole, in which the handle is fastened, andis found ordinarily to contract after being inserted into the socket,therebycausing the handle to work loose. To overcome the loosening ofthe handle and wooden ring with respect to each other I use a metalliccap-disk, D, which ts tightly in socket B and to the handle E, and downagainst the Wooden ring C. It is provided, preferably, with adownwardly-projecting flange, d, on its periphery, which fits intosocket. No contraction of the woody fiber can then possibly create anyl'ooseness in the parts connecting the bristles to the handle. In orderto prevent the loosening of the bristles themselves I form an annularrib, b, on the insideand near the lower end` of socket B. This causesthe wooden ring to bend the bristles laterally toward the socket, and tohold them by a downward pressure against the rib b, while they are alsoheld by lateral pressure against the side of socketand rib. Hence thebristles will be held securely and have no tendency to fall out. Inorder to compress the wooden handle near the bottom and guard as much aspossible against shrinkage I apply a taperA ing metallic ferrule, F,thereto, either driving it thereon by impact or screwing it thereinto bymeans of corresponding threads.

The application is as follows: The bristles are placed evenly around theinside wall of the socket B, while the ferrule F is forced up betweenthem until stopped. The handle E is inserted through the bottom and upthrough the socket and ring, into the latter of which it is driventightly. The cap-disk I) `is then passed over upper end of handle andforced until its downward flange d presses against the inside of socket,while the edge of central hole is made to press against the metallicferrule F, and, if deemed necessary, caused to form an upward flange, f.

This construction gives great strengthand durability, makes but anadditional cost of two cents per brush, and gives much more elasticityto the bristles.

When the inside ot' the brush becomes obstructed by accumulations of anykind the handle may be withdrawn, reversed, and used to relieve it,while the removal or reversal of handle and its insertion through thebrush enables these brushes to be packed fortransportation in aconveniently small space.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The metallic cap-disk I), combined with a socket, handle, and woodenring, as :and for the purpose described.

2. The brush-socket D, provided with the annular inside rib d, arrangedin combination with the ferrule and Wooden ring, as and for the purposesetforth. PHILIPP NVAGNER.
